For the next stop on her "I'm making a comeback" tour, Lindsay Lohan made a guest appearance on "Glee's" two-hour episode on Tuesday ... as herself.

Accompanied by fellow guest stars Perez Hilton and "Entourage's" Rex Lee to portray the judges panel at Nationals, Lohan explained to Hilton that she was there "because I care about young artists chasing their impossible dreams. I know them. I feel them. I was them. So I'm here to support them, unconditionally."

That, and "is there anything better than someone making a comeback?" she inquired. (Don't answer that.)

"Glee" star Amber Riley caused concern when she collapsed on the red carpet Tuesday, but she's since assured everyone that she's just fine.

The 26-year-old actress was walking the carpet while attending a panel discussion in North Hollywood, Celebuzz reports, when she said she was overwhelmed by the flashes from the photographers' cameras.

"Hey guys, I'm okay," she posted to her Twitter account Wednesday. "I got a little dizzy from all the photog flashes! You'd think I's be used to it by now, still a red carpet amateur I guess. Gonna get checked out but I feel fine. Thank you for all the concern and well wishes."

After making the decision to eat healthier seven months ago, "Glee" star Amber Riley has been hitting the red carpet - such as the one rolled out for 26th birthday party in Las Vegas, seen above, last weekend - with a slimmer physique.

The actress told People magazine that chronic stomach pains prompted her to rethink her diet last July.

Instead of fast food and burgers, which Riley said were "attacking" her stomach, "I decided I was going to make a change and eat healthier," she recalled.

Tuesday night's winter finale of "Glee" packed a lot into its hour, including a cliffhanger – and if you haven't seen the latest episode, you might want to skip this post because it's chock-full of spoilers.

Chris Colfer has broken apart from the "Glee" gang to make his starring film debut in the upcoming release, "Struck By Lightning."

The 21-year-old also wrote the coming-of-age comedy, in which he plays a high school student named Carson. Carson is dead set on becoming the "youngest freelance journalist ever to be published in The New York Times, L.A. Times and Chicago Tribune."

But first, he has to get into Northwestern University - and he's not above blackmailing his classmates into helping him get there.
